Heat Your Water Naturally; No Gas, Electricity or Noise!
The Chofu is a precision built wood-burning water heater specifically designed for heating hot tubs.
It heats and circulates water using the principal of thermo-siphon, the movement created by rising hot water, and eliminates the need for a circulating pump or electricity.
Both the outer stove body and firebox are made of high quality #304 stainless steel and the frame and doors are made of cast iron. This combination will guarantee you years of trouble-free service without the danger of burning-out.
The heat from the fire is efficiently transferred to the water through a unique sophisticated construction, making the entire firebox a heat-transferring surface. The total heating efficiency is 14.9 kW.
The smoke outlet on the Chofu features a unique vented collar that provides secondary combustion of un-burned gases that reduces smoke emissions and chimney sparks. The stainless steel stove body surrounding the firebox is a double-walled water-jacket with a 1″ space in-between.
This makes the entire firebox, except the front, a heat-transferring surface. Additional heat transfer takes place in a water-filled baffle plate that runs horizontally through the firebox. The baffle deflects the path of the fire, so it gives up more heat into the water jacket before going up the chimney.
Customers can purchase a stand-alone Chofu Wood Burning Water Heater as a replacement or as an optional hot tub upgrade when purchasing one of Roberts Hot Tubs Complete or Custom Hot Tub Systems.
